Prostate cancer is one of the most common forms of cancer in men. In fact, it is the second leading cause of cancer deaths in men in the United States (Ai, et al. 2016). However, I personally knew very little about prostate cancer. This project prompted an opportunity to learn more about the disease.

Acinar refers to the shape of the cluster of glandular cells (NCI Dictionary).
Histology
A normal prostate consists of three main areas, called zones. There is the peripheral zone, transition zone, and the central zone. In all three zones, both the ducts and acini are lined by secretory cells (McNeal 1988). The peripheral zone, which is the outermost zone, is where the majority of cancers are found. In addition to three zones, the prostate is made up of three types of cells. There are gland cells, muscle cells, and fibrous cells. Muscle cells control urine flow as well as ejaculation, gland cells produce semen, and fibrous cells provide structural support (Anatomy). Adenocarcinoma of the prostate begins with prostatic intraepithelial neoplasia, or PIN. PIN is a pre-cancerous state where cells abnormally proliferate into ducts and acini. There are also larger nuclei present in these cells. However, PIN implies that these cells have not spread into other tissue…
